 PatternSearch2D counts number of occurrences of specific two-dimensional text pattern in text.
 
 The algorithm is implementation of the idea from paper: "A Boyer-Moore Approach for Two-Dimensional Matching"

 This implementation is modified to work with jagged 2D array shapes of pattern and text.
 The expected running time of the algorithm is sub-linear for random texts and patterns.
