Accepts a 1-dimensional struct array (in the format 1xn) and converts it into a cell array. The first row of the cell array has the struct's field names in each column; the data from each of those fields for each entry in the struct array appears in subsequent rows. The idea is to make it easy to prep data for writing to an Excel spreadsheet using xlswrite.
