Procedures:
* deform:: infinitesimal deformations of ideal i
* dim_slocus:: dimension of singular locus of ideal i
* is_active:: is poly f an active element mod id? (id ideal/module)
* is_ci:: is ideal i a complete intersection?
* is_is:: is ideal i an isolated singularity?
* is_reg:: is poly f a regular element mod id? (id ideal/module)
* is_regs:: are gen's of ideal i regular sequence modulo id?
* locstd:: SB for local degree ordering without cancelling units
* milnor:: milnor number of ideal i; (assume i is ICIS in nf)
* nf_icis:: generic combinations of generators; get ICIS in nf
* slocus:: ideal of singular locus of ideal i
* qhspectrum:: spectrum numbers of w-homogeneous polynomial f
* Tjurina:: SB of Tjurina module of ideal i (assume i is ICIS)
* tjurina:: Tjurina number of ideal i (assume i is ICIS)
* T_1:: T^1-module of ideal i
* T_2:: T^2-module of ideal i
* T_12:: T^1- and T^2-module of ideal i
* tangentcone:: compute tangent cone of id
