Rename DataBase Models name

[DiptoChakrabarty]

Currently the database models defined in resume/models.py are lowercase model names (eg experience , education etc)

It would be good if these model names were modified to something like this EducationModel , ExperienceModel etc.
A tablename should be added to these models and also the corresponding models names in other parts of the code should be modified similarly.

The different models present are

• userdetails
• education
• experience
• projects
• skills
• achievements

To contribute send a PR with modifications in one of the above mentioned models of your choice , do not modify multiple models at a single PR.

Check UserModel

Resume-Generator/resume/models.py

Line 12 in 97e3b2d

class UserModel(db.Model,UserMixin):

which currently has been modified for this and the routes and forms are making use of the new model name in the other files
