Add New Stars and Save Output to CSV

Add a New Star to Existing Data with newStar Class

• Users can now add new stars (fix to Issue 1)
• Two methods to add new stars to a plotStereographicProjection() and finalPositionOfStars()

1. newStar(starName=None, ra=None, dec=None, properMotionSpeed=None, properMotionAngle=None, magnitudeVisual=None)

• A new star with a proper motion speed and a proper motion angle

3. newStar(starName=None, ra=None, dec=None, properMotionSpeedRA=None, properMotionSpeedDec=None, magnitudeVisual=None)

• A new star with the proper motion speed for right ascension and declination

userListOfStars -> builtInStars

• Renamed argument userListOfStars to builtInStars

New argument to plotStereographicProjection()

• userDefinedStars: List of newStar objects of stars the user has added
• onlyDisplayUserStars: Only display the stars defined by the users (userDefinedStars)

New argument to finalPositionOfStars()

• userDefinedStars: List of newStar objects of stars the user has added
• onlyDisplayUserStars: Only display the stars defined by the users (userDefinedStars)
• save_to_csv: CSV filename and location to save final star positions with headers ["Star Name", "Right Ascension (HH.MM.SS)", "Declination (DD.SS)"]

New Built-In Star

• Thuban with updated star_data.csv
