Functional analysis: Add MCA function to make cluster column for one dataset

[ChristinaSchmidt1]

Input: DMA results
Parameters: You can pass selection column (e.g. Log2FC, p.adj, t.val,...)
Usage: Based on the selection parameters we assign a cluster name (New column "Cluster" will be added to DF). E.g. if Log2F cutoff = 1 and p.adj cutoff = 0.05, metabolites with Log2FC > 1 and p.adj <0.05 will get the assigned "UP",...

If CoRe=TRUE, we can do this by taking into account also the release/conusmed column.

We could add something simple automatically to the DMA function results.
