dimnames_intersect: Intersect the dimension-names of two arrays.
In LAJordanger/leanRcoding: Leaner R Coding

When a part of one array should be extracted and included into another array, one might need to use an intersection of the dimension-names approach to figure out the correct argument to be used by restrict_array. Note that the order of the arguments does matter, since it's dimnames1 that decides the format of the resulting intersection. Warning: The result of this function can be an empty list, so keep in mind that your code can deal with that if you want to use this in a function.

1	dimnames_intersect(dimnames1, dimnames2)

`dimnames1`	The dimension names of the first array, the order of the names of the dimension-names of the result will be decided by this.
`dimnames2`	The dimension names of the second array.

A list with the common parts from dimnames1 and dimnames2 is returned. The result will an empty list when no dimension-names are common, but it will also be empty if a common dimension-name has no common values stored.
