Adjustments to match IEGenLib changes

[riftEmber]

As IEGenLib development continues and features/assumptions that spf-ie uses change, spf-ie also needs to. This issue will be a running list of those changes, which I will tackle when I return to this project.

• adjust to new Computation memory management, in which everything is a heap pointer managed manually
• wrap data space names in some sort of delimiter like $'s so that find-and-replace on data space names will not affect actual code. Note as a limitation to the user that they cannot use whatever the delimiter is in their code.
• give Computations their parameter lists
• set up empty iterspaces/execschedules correctly, as having a single constant element instead of being empty (check on this for iterspaces)
• do something different with compound array accesses?
• printInfo doesn't print anymore, it gens a string this doesn't seem to be the case
• take if statements as blocks if their condition involves data spaces (clarify on this), if it has multiple conditions, separate out ones that need to be blocks
