* Compares 2 sets of grid fragments to each other and checks if they have the same
* general geometry.
* This means that things like areas, area names or line names are ignored.
* This only checks if the 2 sets of fragments have as many fragments, as many lines, and
* that those lines are at the same distance.
*
* @param {Array} fragments1
* A list of gridFragment objects.
* @param {Array} fragments2
* Another list of gridFragment objects to compare to the first list.
* @return {Boolean}
* True if the fragments are the same, false otherwise.
