made changes in layouts

Changed the layouts to highlight monthly and daily stats as headings.
Also added a label describing what the button in track stats are
supposed to do.
Fixed the expense addition to only take amounts accurate up to 2 decimal
places
updated track status

Updated track status to show total expenses as per the stat variant
chosen in the spinner
added description column in database

Added a column to add a description for an expense if need be.
Accordingly updated all the required files.
updated layout for new column
started work on removing records

Added the layout and all supporting views required for the removal of an
expense. Still need to provide the core functionality to remove the
expense from the database, but all the supportive views like the spinner
and table are there. Table population works perfectly.
basic removal implemented

Implemented the removal of an expense with basic functionality, i.e., it
just removes the record and displays the updated table. Need to
implement the updating of the entry id's of the remaining records
Expenses removal complete

Fully implemented the removal of an expense along with the updating of
the entry id's of the records that follow the record which was removed.
fixed expense removal

Fixed a small bug in expense removal where the entry id wasn't getting
correctly updated. Also refined the UI a bit to refresh to entry fields
in addExpense and removeExpense
trying themes

Started a new app to try themes
changed base theme of BudgetMe
