[revert] Reverted the dbdisp tree to the previous development stage where the
display of the variable criterion was completed partially.

This tree had been backtracked to a previous commit simply for the reasons of allowing the merge into master,
because part of the tree was production ready.
Merge branch 'dbdisppage' of https://github.com/icyflame/alum-cell-erp into dbdisppage
Revert "[backtrack] Backtracked several commits to ensure that code pushed to master is"

Had performed this commit so as to ensure that this branch was production ready and could be pushed to master.

This reverts commit e5c08ac31c93fb52ac347a98e7506e0a9438bb12.
[minor] changes in the rendering of the button group
Used switch case instead of if elseif statements for assigning the class variables.
[added-feature] Added a feature to add the active class for all the qualifiers.

Got an idea for implementing the links of the qualifiers.

Store a variable in the data for the current page called current year.

Since year is the only variable that we are confused about, it will be good enough to
use that.
[solved] Completed the second phase of the database display.

Now the database can be viewed and can be sorted using any of the years and any
of the four qualifiers.
Merge pull request #7 from icyflame/dbdisppage
