This Challenge is to verify a Criss-Cross matrix has no invalid words,contains all of the word set, and all are simply connected (Up/Down/Left/Right). Separation, UDLR, must exist between non-intersecting words. Diagonal is considered separate.
The word set is a cell array. The matrix is an array of Char with spaces being represented by '`', char(96), which is under the tilde on my keyboard.
Achar=['abcd' '``a`' '``g`'];
Output: Validity (1 for Valid, 0 for Invalid)
