subplotplus() - Enhanced layout MATLAB subplot function

[subplot_handles,LabelsFontSize] = subplotplus(subplot_array,varargin) is an enhanced alternative to the inherit subplot() function of MATLAB. Using subplotplus() almost any layout of subplots can be created in a particular figure.
The desired subplot layout is described using a complex cell array where each "atomic" cell, within the cell array, corresponds to a subplot. The function scans the content of the input cell array and builds the desired matching subplot layout in the figure. The size, alignment and font size of the subplots is automatically adjusted for best appearance.
The function is recursive in nature so any level of subplot divisions can be created. The returned arguments are the created subplot handles as well as the optimal label (X and Y) font size that should be used for a specific subplot for best appearance.

Input arguments:
+ subplot_array: A cell array that describes the desired subplot layput. For example, a 1x2 subplot layout where the right-end subplot is further divided down to a column of 3 additional subplots is described by the following cell expression: {{[]},{{[]};{[]};{[]}}}.
A group of subplot cells, sharing the same "parent" cell, can be glued together in order to save figure space using the '-g' option string at the cell's content (instead of empty group []). For example, if the 3 columned subplots of the previous example are to be glued together, sharing the same X-axis, the follwing cell expression should be used:
{{[]},{{['...-g...']};{['...-g...']};{['...-g...']}}}.
+ varargin: only used for function recursion and should not be used by the user.

Output arguments:
+ subplot_handles: A list of the created subplot handles by their order of appearnace in the figure, starting from the left-top corner in a clockwise manner.
+ LabelsFontSize: A matching list of X/Y-axis optimal labels size for further user work on the subplots.
