clearCache -- creates a new divisor with most entries from the cache removed

Usage:

clearCache( D1 )
Inputs:
- D1, an instance of the type BasicDivisor,
Outputs:
- an instance of the type BasicDivisor,

Description

This function returns a divisor where the only entries left in the cache is the key ideals (which points to how the ideals should be displayed to the user).

i1 : R = QQ[x,y,z];

i2 : D = divisor(x);

o2 : WeilDivisor on R

i3 : isPrincipal(D)

o3 = true

i4 : peek (D#cache)

o4 = CacheTable{ideals => MutableHashTable{...1...}}
                isPrincipal => {false, true}
                                    1
                divisorToModule => R

i5 : E = clearCache(D);

o5 : WeilDivisor on R

i6 : peek (E#cache)

o6 = CacheTable{ideals => MutableHashTable{...1...}}

Ways to use clearCache:

clearCache(BasicDivisor)
