Describe the EqEx specs

depends on #2

[Nircek]

All the EqEx issues is moved to the pikne-zadania-exercises repo. This issue will be closed when the v0.1 will be released (Pikne-Programy/pikne-zadania-exercises#1).

I have decided to write the EqEx spec in the Wiki of this repo, so it's here.

There is still a lack in the documentation. We should add info about using LaTeX and be more specific in the calculation process description.

Due to that, I think we can keep this issue open and figure out how to add images in v0.2 EqEx specs. In my opinion, the best way will be adding img folder in each subject folder and add relative to it paths in exercise files.

[Nircek]

It should be stated that img refer to the path relative to the /api/static/:subject/ (see #23 (comment))

Units like 1/s should be written as /s in EqEx format.
For example, T=10/s would be rendered as .

I've finished writing the specification. You can check it out here.
