Possible improvements for future

[pacharanero]

• review bug on Safari for size of the chart/zoom level #83
• results table needs some more improvements to look better and have copy and paste of the data #82
• toggle between SDS and centile charts still happens when results are showing - need to disable the SDS/centile toggle button #81
• react-demo-client is currently an iframe in the docs site - we could try to embed the React directly? #77
• the form side of the page is a bit clunky and could do with improvement #78
• 'UK-WHO' label on the Reference dropdown could be a bit clearer that it is the standard chart for all children that are not Down/Turner syndrome #79
• Default sex issue rumbles on, turning into a gender politics issue that we will never resolve #80
• Demo client should use full width of the page in the documentation site #84
• Bottom of the left hand table should line up with the bottom of the chart on the right #85
