convertCharArray

convertCharArray
   Converts input to make sure it is a cell array of character vectors.
   String arrays are transformed into character vectors, and if only one
   character vector is given. Output is always a cell array, also if only
   one character vector is given as input.

   Input:
   funcInput          function input that should be checked

   Output:
   inputConverted      cell array of character vectors
