ExIR Shiny app is updated according to the ExIR function.

ExIR visualization function, exir.vis, is optimized.

The package vignettes are updated and the fcor function described and exemplified in the vignettes.

The ExIR function is optimized (corrected for proper Spearman correlation analysis and added Mutual rank as a measure for filtering top correlations) and speeded up (using the data.table package).

A function named fcor is added to the package for super-fast correlation analysis of large datasets and simultaneous P-value and Mutual Rank calculations.
