TableViewer App added to suite

TableViewer App is a MatlabTM App to load tabular data from text files, spreadsheets and data held in a .mat files. This allows the rapid viewing of a range of default plots, interactive plotting and statistics tools and the ability to add bespoke analysis and plotting. The latter has the advantage that the functions and outputs can be more clearly documented than is often the case in a spreadsheet, thereby maintaining the history (especially if the functions are maintained in a version control repository, such as git or svn). If the latter is the intended use, you can clone TableViewer from github at https://github.com/CoastalSEA, if you want to build and maintain your own version of the App. Alternatively, you can create a branch and contribute your additions to the development.
