[galaxy-dev] new tool: calculate frequencies

Hi, Attached is a tool to calculate frequencies/distribution of values in a column (similar to "histogram" tool, but without plotting the chart). The tool allows finer control of the output, by setting min,max,bin-width or number-of-bins. This allows calculating distribution of multiple datasets, then comparing them or plotting them all together with the plotting tool.
