	initialize environment. Gridworld is defined as matrix A of size width by height. So, internally, it is accessed as A[x][y] with x ranging from 0 to width-1 and and y from 0 to height-1 Each element in A[x][y] is unsigned char. A[x][y] = 0 corresponds to fully traversable and cost is just Euclidean distance The cost of transition between two neighboring cells is EuclideanDistance(max(A[sourcex][sourcey],A[targetx][targety])+1) f A[x][y] >= obsthresh, then in the above equation it is assumed to be infinite. The cost also incorporates the length of a motion primitive and its cost_multiplier (see getcost function) mapdata is a pointer to the values of A. If it is null, then A is initialized to all zeros.
