Validation on data input

[rmroot]

Each of the data input forms should have validation hooked up to it. That would most likely entail converting the forms from template driven forms to reactive forms using Angular's form builder. Using services to build the forms will allow validation checks throughout the application and better messaging for the user on missing or invalid data.

Best approach will probably be to break down the PR's work by type:

• Company
• Facility
• Assessment
• Project

I started the groundwork for converting the contacts form from a template driven form to a reactive form. I've added the service that can be re-used for contact validation. Going to handoff to @RLiNREL for him to run with as a first issue. Work was done on branch: issue-65

We will probably want to convert this issue to an epic and create separate issues for each form that needs to be done. We can discuss.

Some additional notes on the changes I made:

• The Form Group object return by the service has the validation for the form in it and has an "invalid" property that can be used to check that data input is valid. I have an example of this being used to disable the next button and show an alert exclamation point in the form. We will want to replicate this sort of behavior in the sidebar as well.
• I did the name for the form and the rest of the data can be added by Roy
• While going through these I think it's a good time to evaluate the data members for each form, make sure that we have ranges for validation and the correct data present.
• Form service: company-contacts-form.service.ts
• Form component: company-contacts-form.component.ts
