Also described are methods for controlling the growth of weeds by applying an auximc herbicide to which the auximc herbicide -tolerant plants described herein are tolerant. AUXINIC HERBICIDE-TOLERANT PLANTS RELATED APPLICATIONS This application claims priority under 35 U.S.C. § 119 to U.S. Provisional Patent Application No. U.S. 61/759,099, that was filed on January 31, 2013, and is incorporated by reference herein in its entirety. TECHNICAL FIELD This application relates to the field of agriculture, particularly to auxinic herbicide- tolerant plants. BACKGROUND Auxinic herbicide tolerance has been reported as occurring in weeds, such as Kochia and Charlock, but not in Brassica crop plants, such as domesticated B. napus, B. rapa, or B.juncea. See, e.g., Nandula and Mathey (2002); Jugulam et al. (2005). Attempts have been made to provide an auxinic herbicide tolerance trait for use in Brassica crop plants, but to date these have not been demonstrated to provide a commercial level of herbicide tolerance in such plants; moreover, these attempts have involved transgenic insertion of exogenous auxinic herbicide tolerance trait genes. See, e.g., U.S. Patent Nos. 8,071,847 and 8,603,755. The herbicide tolerance of the mustard weed reported by Jugulam et al. (2005) has, despite intense efforts, eluded discovery and thus has not been successfully transferred into crop plants. See, e.g., Jugulam et al. (2005); Jasienuik et al. (1995). It would be useful to obtain crop plants that possess auxinic herbicide tolerance. Yet, lacking definitive information as to which gene, gene product, or mechanism of action may be involved in such tolerance in the above-described weeds, it has not been possible to leverage this discovery in mustard weed to a useful application in crop plants. Thus, there remains a need for Brassica crop plants exhibiting a commercial level of tolerance to auxinic herbicide(s), and for such auxinic herbicide tolerant Brassica crop plants that are non-transgenic, as well as for plant parts, seeds, and products thereof. BRIEF SUMMARY One embodiment described herein is an auxinic herbicide tolerant crop plant having a commercial level of tolerance to an auxinic herbicide. Another aspect described herein is a non- transgenic auxinic herbicide tolerant crop plant having a commercial level of tolerance to an auxinic herbicide. Another embodiment described herein is an auxinic herbicide tolerant plant or plant part thereof having the auxinic herbicide-tolerance characteristic of any of Sinapis arvensis lines DT- 0 1 SA2-R or DT-01 BC8SA2-R, a representative sample of seed of each line having been deposited with American Type Culture Collection (ATCC) under Patent Deposit Designation Numbers PTA-1 1213 and PTA-1 1214, respectively, with the proviso that the plant is a monocot or dicot species other than Sinapis arvensis. In one aspect, the auxinic herbicide tolerance trait is referred to as "DART." Lines DT-01 SA2-R and DT-01 BC8SA2-R also are known as "SaParR" and "SaBC8R," respectively. Another embodiment described herein is a nucleic acid comprising: (a) a chimeric polynucleotide comprising both Sinapis arvensis nucleotide sequence and Brassica nucleotide sequence, wherein said polynucleotide encodes the DART trait of any of lines DT-01 Cyc2 BNS4, DT-01 BC3Bn#13, DT-01 BC4Bn#13-l, DT-01 BC5Bn#13-l-18, DT-01 SA2-R, or DT- 0 1 BC8SA2-R, a representative sample of seed of each line having been deposited with American Type Culture Collection (ATCC) under Patent Deposit Designation Numbers PTA- 120132, PTA-1 121 1, PTA-12050, PTA-1 1212, PTA-1 1213, and PTA-1 1214, respectively; or (b) a mutagenized or recombinant polynucleotide encoding the DART trait of any of lines DT-01 Cyc2 BNS4, DT-01 BC3Bn#13, DT-01 BC4Bn#13-l, DT-01 BC5Bn#13-l-18, DT-01 SA2-R, or DT-01 BC8SA2-R, a representative sample of seed of each line having been deposited with ATCC under Patent Deposit Designation Numbers PTA-120132, PTA-1 121 1, PTA-12050, PTA- 11212, PTA-1 1213, and PTA-1 1214, respectively. In one aspect, the DART trait is encoded by the Sinapis arvensis polynucleotide. In another aspect, the nucleic acid encodes a functional DART trait, said nucleic acid comprising (a) a nucleotide sequences according to any one of SEQ ID NOs:8, 12, 16, 18, 22, 26, 30, 34, 36, 40, 44, 48, 52, 56, 62, 66, 76, or 80; or (b) a nucleotide sequence encoding a polypeptide comprising an amino acid sequence according to any one of SEQ ID NOs:9, 13, 17, 19, 23, 27, 31, 35, 37, 41, 45, 49, 53, 57, 63, 67, 77, or 81, respectively; or a mature form thereof. In some aspects, a nucleotide sequence encoding the amino acid sequence is at least 90% homologous to any one of SEQ ID NOs:8, 12, 16, 18, 22, 26, 30, 34, 36, 40, 44, 48, 52, 56, 62, 66, 76, or 80, or a synonymous codon substituted variant thereof. In other aspects, the encoded amino acid sequence is 70%> homologous to any one of SEQ ID NOs:9, 13, 17, 19, 23, 27, 31, 35, 37, 41, 45, 49, 53, 57, 63, 67, 77, or 81, or a mature form thereof. In another aspect, the polynucleotide is isolated. In another aspect, the nucleic acid is operably linked to a promoter operable in plant cells capable of expressing the polypeptide encoded by the nucleic acid, the expression of the polypeptide conferring to the plant or cell tolerance to an auxinic herbicide. Another embodiment described herein is an auxinic herbicide tolerant plant or plant part thereof having the auxinic herbicide-tolerance characteristic of any of Brassica napus lines DT- 0 1 Cyc2 BNS4, DT-01 BC3Bn#13, DT-01 BC4Bn#13-l, or DT-01 BC5Bn#13-l-18, a representative sample of seed of each line having been deposited with American Type Culture Collection (ATCC) under Patent Deposit Designation Numbers PTA-120132, PTA-1 121 1, PTA- 12050, and PTA-1 1212, respectively, with the proviso that the plant is a monocot or dicot species other than Sinapis arvensis; and wherein the auxinic herbicide tolerance is greater than that exhibited by a wild type variety of said plant lacking said auxinic herbicide tolerance. Introgressed Brassica napus lines containing an auxinic herbicide tolerant trait include DT-01 Cyc2 BNS4, DT-01 BC3Bn#13, DT-01 BC4Bn#13-l, and DT-01 BC5Bn#13-l-18.
