Installation page added

[ayushya19]

I have taken content from the gtsam website and from the doxygen docs to insert content on the subtopics Importing "GTSAM in your projects" and "Installing"

Thanks !!! I'd like to check out your branch and check it out.
It's been a while since I looked at rtd, though. What are the steps to render/view ?

[varunagrawal]

@dellaert the steps involved are

git checkout rtd-docs
cd docs
make html
# For Linux
xdg-open build/html/index.html
# For Mac
open build/html/index.html

@ayushya19 I think you have committed the wrong files. Your PR includes the build directory which is created when we run make html. You probably intended to update and commit the docs/source/Installing.rst file.

@ayushya19 are you still intent on completing this PR?

[ayushya19]

Hey @varunagrawal ,

Sorry for the late responses. I have the files ready.

Just have been a lil caught up. I'll push the changes as soonas I get a chance.

@ayushya19 any updates?
