Calculate dissimilarity distribution of two sequences

Explanation

Input: In the folder "./data", and we did some preprocessing towards these data. (Include load the data, and cut the unnecessary string;
Output: The dissimilarity distribution of the sequence group A.
explanation of dissimililarity distribution: We used edit distance algorithm, to align all the sequences from sequence group A and sequence group B, and calculate the no alignment bases in the sequences A. Accumulate all the no alignment bases in each position.
