Remove cAndCwithStickyE project files

[mnwhite]

Per team discussions, projects like cAndCwithStickyE should live only in their own REMARK, not duplicated in the package distribution of HARK. This commit removes the project files for StickyE.

I will do this when we have verified that everything works properly for a fresh install. Probably nearly there now, but this issue needs to be fixed (on the cAndCwithStickyE-Latest private repo). When that is done, I'll run my scripts again to generate the public version.

I'd also like to do a global search in HARK, DemARK, and REMARK for things that might break.

This is the only repository in the econ-ark organization with a reference to HARK/cAndCwithStickyE:

https://github.com/econ-ark/econ-ark-make/search?q=cAndCwithStickyE&unscoped_q=cAndCwithStickyE
It is a checklist with no functionality.

The other references to cAndCwithStickyE are to the llorracc/cAndCwithStickyE version, which is a REMARK:

https://github.com/econ-ark/REMARK-make/search?q=cAndCwithStickyE&unscoped_q=cAndCwithStickyE

Or the paper:

https://github.com/econ-ark/PARK-make/search?q=cAndCwithStickyE&unscoped_q=cAndCwithStickyE
https://github.com/econ-ark/HARK-make/search?utf8=%E2%9C%93&q=cAndCwithStickyE&type=
https://github.com/econ-ark/PLUTARK/search?q=cAndCwithStickyE&unscoped_q=cAndCwithStickyE

In other words, I could find no reason to think removing these HARK files would break downstream code.
