`add` command for adding tasks is really long and prone to errors

[nus-pe-bot]

Adding a tasks requires filling in many parameters. Additionally, many of such parameters have strict requirements to them (date must be correct format, time must be correct format, end date cannot be before start date, etc...).

It becomes hard to use for new users, and also inputting something wrong (which might be quite common for new users) requires them to re-enter to whole command again, which can be troublesome and annoying.

Team's Response

The current feature to enable users to reduce the restrictions when filling in the parameters will require additional resources and expertise to handle them, and is not within the capabilities of our current version. Furthermore, the restrictions, e.g. end date before start time, adding of task cannot have clashes with current task list, are completely acceptable.
